Abstract
Organo-tin compound having the formula I:[R—(Y)a]b—SnX4-b wherein R stands for a polycyclic hydrocarbyl residue which optionally carries one or several substituents; Y stands for a bivalent linker group; X represents a hydrolysable group; a is an integer 0 or 1; and b is an integer 1 or 2. The preferably stands for an unsubstituted or substituted fused hydrocarbon ring system selected from naphthalene, antracene, phenanthrene, and pentacene. The novel compounds are useful for producing polymers which can be employed as thin film materials in optoelectronic devices.
