Abstract
The present disclosure is directed, in general, to nonlinear optical (NLO) chromophores comprising donating groups of the following general structure (D1): where R1 can be a substituted or unsubstituted aryl or a substituted or unsubstituted alkyl. R2 can be a substituted or unsubstituted aryl, a substituted or unsubstituted alkyl or a ring-locked structure. In some embodiments, R1 and R2 can together form a ring structure. In some embodiments, R2 can be a ring-locked structure forming a ring with the phenyl group of the formula (D1). In certain embodiments, n is 1 or 2.
