| titleOfInvention | Blue light frequency-doubling luminescent material and its preparation method and application based on naphtho- indenes carbazole unit |
| abstract | The invention belongs to organic photoelectric technical field, a kind of blue light frequency-doubling luminescent material based on naphtho- indenes carbazole unit and its preparation method and application are disclosed.The luminescent material has structure as follows: Wherein R be aryl, triphenylamine base, the linear or branched alkyl group of carbon atom number 1~20 or carbon atom number 1~20 alkoxy, 0 < x≤1, polymerization degree n be 1~300.Since the conjugate length of naphtho- indenes carbazole unit is big in the present invention, and polynary condensed cyclic structure keeps its rigidity strong, and stability is good；Meanwhile polymer can realize the blue emission of preferable excitation purity, fluorescence quantum yield is high, is conducive to the efficiency for improving blue light material device. |
