We are excited to share the success of Rajendra Kumar Konidena’s first-time independent article in ChemComm; “A streamlined steric-shielding approach toward efficient narrowband (FWHM ∼ 18 nm) ultra-violet emitters for OLEDs” included in the full milestones collection.
Read our interview with Rajendra below.
What are the main areas of research in your lab and what motivated you to take this direction?
Replacing traditional metal-based functional materials with purely organic alternatives in energy-related optoelectronic devices and biomedical applications is one of the current key goals of chemical sciences research. Despite their advantages in cost-effectiveness and environmental sustainability, achieving high performance demands a deep understanding of the interplay between molecular structure and functional properties. Driven by this challenge, our group — the Organic Materials Laboratory (OM-Lab) at IIT Patna — is dedicated to designing and synthesizing innovative organic building blocks and exploring their structure–property correlations and device performances. Our long-term vision is to develop efficient organic materials that can enable real-world devices with significant technological and societal impact.
Can you set this article in a wider context?
Developing metal-free, purely organic narrowband ultraviolet (UV) emitters with emission < 380 nm remains a significant challenge. UV emitters are not just important in lighting and display technologies— they also play key roles in sterilization, sensing, photocatalysis, and biomedical imaging. Traditional approaches often rely on complex boron-based systems, which limit scalability and sustainability. Our work addresses this gap by introducing a simple, yet versatile, molecular design by combining two rigid organic building blocks — indolocarbazole and carbazole — in a sterically controlled, non-conjugated fashion. This design unveiled a new molecule that produces sharp, color-pure UV emission with an impressively narrow bandwidth. This study highlights how smart molecular engineering can lead to cost-effective, sustainable, and high-performance organic materials that could power the next wave of optoelectronics.
What do you hope your lab can achieve in the coming year?
The group has now grown to a substantial size, and individual research projects are gaining momentum. In the coming year, I hope our lab will continue to explore new molecular designs and synthesize new heterocyclic building blocks that challenge the boundaries of what organic materials can do. My vision is that each discovery from our lab should bring us a step closer to being both scientifically exciting and technologically impactful.
Describe your journey to becoming an independent researcher.
There have been many crucial moments that have shaped my journey to where I am today, and I am deeply grateful to the many people who have supported me along the way—especially my supervisors. Their invaluable guidance and mentorship have played a central role in shaping me into the scientist I am today.
I earned my Ph.D. in 2017 under the guidance of Prof. K. R. Justin Thomas at IIT Roorkee, where I developed a keen interest in functional organic materials for optoelectronic applications. Following my Ph.D., I held a NRF-sponsored Postdoctoral Fellowship in Prof. Jun Yeob Lee’s group at Sungkyunkwan University, South Korea, where I explored advanced organic emitters for modern displays. I then worked with Prof. X. L. Feng at TU Dresden, Germany, and later with Prof. Jangwook Park in South Korea. Subsequently, I joined Prof. Takuma Yasuda’s group at Kyushu University, Japan, where I developed multiresonant TADF materials for OLEDs. Across these experiences, I gained deep expertise in the rational design, synthesis, and structure–property studies of organic functional materials, which have become the foundation of my research philosophy. Motivated to translate these experiences into a distinct research vision, I established the independent research group, named OM-Lab at IIT Patna in 2024.
What is the best piece of advice you have ever been given?
I’ve been fortunate to receive valuable advice from many mentors, but the quote immediately come to mind while reading this is from my Ph.D. advisor, Prof. Justin: “Keep trying until you succeed” It continues to shape my approach to research and life.
Why did you choose to publish in ChemComm?
I chose ChemComm for its strong reputation in publishing high-quality, interdisciplinary, and cutting-edge research. Its broad and diverse readership also provides an excellent platform to maximize the visibility and impact of our work
