ABSTRACT: The combination of a boryl group and an amino group connected via aromatic or conjugated
olefinic n-systems leads to the formation of the following novel, structurally different types of organic
boron-nitrogen dyes B,N tnarylmethane dyes, B,N cross-conjugated indigo systems and annaromatic B,N
pentalenes have been synthesized and characterized for the first time after then- spectroscopic properties had been calculated All of these dyes havmg the B,N chromophoric system show very interesting
spectroscopical properties Potential optoelectronic applications are discussed.
