Abstract:
Chromophores possessing excited-state intramolecular proton transfer (ESIPT) are of great important in the past decades because of their desirable unique photophysical properties which can be used in various applications ranging from optoelectronic devices such as light emitting diodes and laser dyes, molecular switching to fluorescent probes both in chemical and biological systems. Therefore, the development of new chromophores based on the ESIPT process have been intensively developed using combined experimental approach and theoretical study. The identification of how structural modifications controlling their optical properties driven by ESIPT process and solvent media affecting their fluorescent emission are of great importance. Thus, our group is interested in studying several aspects in terms of electronic properties and ESIPT process through the computational chemistry as an effective tool. Moreover, the systemic study and molecular screening using certain criteria will be carried out to provide the best candidates for applications in fluorescent probes and imaging agents.
