New types of "X-type" NLO dendrimers, C2 and C3, in which the chromophore moieties were arranged in order, were rationally designed. The special topology of the chromophore moieties contributed a great deal to the good NLO performance of C2 and C3: the d33 value of C2 (containing only five chromophore moieties) was 157.4 pm V-1, while that of C3 (containing nine chromophore moieties) achieved 195.2 pm V-1, much larger than that of C1 (74.7 pm V-1, containing three chromophore moieties) and the fifth generation dendrimer (G5) (193.1 pm V-1, bearing 62 pieces of chromophore moieties). Through careful experimental and theoretical analysis, their structure-property relationship was explained, and discussed in detail.

The present invention provides compounds of the formula (I): C-Q-O-Si (R1)(R2)-N wherein C is a chromophore; Q is selected from the group consisting of optionally substituted aliphatic, aryl, heteroaryl, cycloalkyl or heterocycloalkyl; R1 and R2 are independently selected from the group consisting of optionally substituted C1-8 alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, C1-8 alkyloxy, cycloalkyloxy, heterocycloalkyloxy, alkylsilyloxy and arylsilyloxy; and N is a glycosylamine or abasic moiety.
