Paper Abstract

By using inclusion chemistry, low-molecular-weight organic materials such as 8-hydroxy-quinoline derivative-metal complexes (ZnQ2, AlQ3) were encapsulated by t-butyloxycarbonyloxy (t-BOC)-protected β-cyclodextrin to increase their processibility and to protect them against atmospheric environment. Since the products showed increased solubility in common organic solvents such as tetrahydrofuran, methylenechloride, and chloroform, they could be processed by solution method like spin-coating. Their absorbance and emission spectra were nearly the same compared to their unmodified coordinated complex. By using deprotection reactions of t-BOC groups, these materials were patterned by a simple photolithographic process.
