Abstract
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.
Highlights
For photosynthesis light with the wavelengths from 400-700nm is necessary
Since the optimum light intensity and light are essential for optimum plant growth and development, much effort is focused on the development of transparent greenhouse covering material with improved optical properties [2]
The synth esized blue fluorescent was examined photophysical properties which is important to light c onversion and studied used of density functional theory (DET) calculations at the B3LYP/6
Summary
For photosynthesis light with the wavelengths from 400-700nm is necessary. This part of the global radiation is called photosynthetically active radiation (PAR) [1]. Light conversion films have been actively developed and are gaining much attention. Light conversion film is a material that converts the less active wavelength band in photosynthesis to the more active wavelength of 400-700 nm. Plant growth under the light conversion film had not yet been sufficiently reviewed due to the difficulty in developing a durable and weather-resistant film [3]. Naphthalimide derivatives with ethynyllink was synthesized blue fluorescent and studied for apply light conversion film. The synth esized blue fluorescent was examined photophysical properties which is important to light c onversion and studied used of density functional theory (DET) calculations at the B3LYP/6-.
