摘要：Herein, a molecular pixel system for full-color luminescence reproduction is achieved by adjusting the colorless mixtures of two matching fluorophores, i.e., polarity-insensitive 9,14-diphenyl-9,14-dihydrodibenzo[a,c]phenazine (DPAC) as the fixed red primary color and polarity-sensitive dansylamide (DSA) as dynamic blue to green primary colors. DPAC and DSA possess independent emission properties free from electron and energy transfer crosstalk between them because of their close frontier molecular orbitals as well as similar absorptions below 400 nm. According to the additive color theory, under diverse mixing ratios and various polarities, a smooth emission color change is realized in the triangle surrounded by the luminophores in the chromaticity diagram with accurate prediction and expedient reproduction. The principle of this system may open an innovative route for the development of powerful full-color luminescent materials, for example, ratiometric fluorescent polarity sensors and invisible fluorescent crayons.
