Novel Ethyne-Linked Compounds Containing 1,8-Naphthalimide Group for Light Conversion Film

In order to regulate plant growth, we studied blue fluorescent for agriculture light conversion films. The light conversion film containing blue fluorescent can convert ultraviolet (UV) and violet light (300-400 nm) into the blue-green light (400-500 nm) which is the more active wavelength band in photosynthesis. A durable and weather-resistance is important properties for applicate agriculture light conversion films.1,8-naphthalimide derivatives usually exhibit strong fluorescent emission on irradiation, excellent photoluminescence (PL) quantum efficiency, good photo-stability and film-forming properties as well as desirable chemical and thermal stabilities. In this study, 1,8-naphthalimide derivatives containing ethynyl link were synthesized and characterized. Synthesized fluorescent has high thermal stability and suitable photophysical properties for agriculture light conversion films
