Objectives & Goals

Our aim is to develop lost cost organic sensors that can sense chemicals using the triplet states of the materials. We have established how the self-charge transfer complexes (SCTCs) of a single-component organic conjugate can be used in chemical sensing applications. We are currently looking into ways to take advantage of this novel strategy and new systems in bio-imaging of hyperoxia and hypoxia applications. Further, the group has also developed mechano-luminescent emitters that show modulation of dual emission via TADF and RTP using mechanical stress. We have demonstrated that mechanical effects can modulate the excited triplet states (for example, T2). We intend to use these systems for further development of mechano-phosphors.
