酸性介质中质子化的卟啉单元形成可电泳的物种,利用该性质通过电化学方法制备了卟啉-苝酰亚胺分子阵列的固体薄膜.吸收光谱证明吸附的酸能够在薄膜形成后可逆地排除,AFM测试结果表明得到了均匀的卟啉-苝酰亚胺分子阵列薄膜.这项工作为解决大型分子阵列因溶解度低而不能溶液加工成膜、因升华温度太高而不能通过真空气相沉积制备薄膜的难题开辟了新的路线. The protonated porphyrin units in an acidic medium form electrophoretic species by which a solid thin film of the porphyrin-perylene-imide molecular array is prepared. The absorption spectra demonstrate that the adsorbed acid can reversibly AFM test results showed that a uniform porphyrin-perylene imide molecular array film was obtained.This work is to solve the problem of large molecular arrays can not be formed into films due to low solubility and can not be processed by vacuum vapor deposition because the sublimation temperature is too high The difficulty of preparing the film opened up a new line.
