人们虽然早就知道物质因吸收光能引起了各种各样的化学变化,但是把光作为有机合成的能源来着手研究却是本世纪初期才开始的。尽管有机光化学的研究起步很晚,但发展却是异常迅速。现在,在这方面已积累了丰富的理论知识,这些理论知识在高分子中已得到广 Although people have long been aware that substances cause a wide variety of chemical changes due to the absorption of light energy, it is only at the beginning of this century that the study of light as an energy source for organic synthesis begins. Although the research on organic photochemistry started very late, the development is extremely rapid. Now, in this area has accumulated a wealth of theoretical knowledge, these theoretical knowledge has been widely used in polymers
