Abstract: | This study deals with photodegradation and metastability of polysilylenes. Physical properties of chemically prepared poly [methyl(phenyl)silylene] and polysilylenes prepared in radio-frequency and microwave discharges are compared. The position and width of the photoluminescence band due to the main chain excitations for both materials preserve but its intensity strongly depends on the preparation conditions and changes considerably during the photodegradation. The difference in photodegradation rate of both materials is explained by their different susceptibility to silyl radical formation and reverse recombination due to the chain and side groups rigidity. | ||||||||||
