This work presents a new amino-SBBF (ASBBF) library that consists of various alkyl-amines and aromatic-amines on the electron-donating site. The synthesis, photophysical properties, quantum chemical calculation, two-photon responsiveness, and bioimaging applicability of ASBBF in cells were successfully identified. This study provides guidance for the development of new fluorescent materials and molecular probes in various research fields.
Single benzene-based fluorophore (SBBF) is a representative small-size fluorescent dye which has an electron push-pull structure within a benzene backbone. In this work, we disclosed a new amino-SBBF (ASBBF) library that has various alkyl-amines and aromatic-amines on the electron-donating site. The synthesis, photophysical properties, quantum chemical calculation, two-photon responsiveness, and bioimaging applicability of ASBBF in cells were successfully identified. We believe that our present work provides a guide to the development of new fluorescent materials and molecular probes in various research fields.
