A general strategy for development of a single benzene fluorophore with full-color-tunable, environmentally insensitive, and two-photon solid-state emission

Abstract

We report here a single-benzene based fluorescent framework, amino-terephthalonitrile, denoted SB-Fluor. This scaffold displays versatile emission wavelength tunability via structure modification, covering the full visible light spectrum, both in the solution and solid state. Moreover, one molecule, SBF3, exhibits polymorphism-dependent reversible mechanochromic luminescence.
