Claims28
A semiconductor compound of a formula
- wherein R1, R2 and R3 are independently selected from H, alkyl, fluorosubstituted alkyl, heterocyclic, aryl and fluorosubstituted aryl moieties, said alkyl and fluorosubstituted alkyl moieties ranging from about C2 to about C10;
- each said x is an integer independently ranging from about 0 to about 8;
- and z is an integer selected from 0 and integers greater than 0, where at least one of x, y an z is selected from 2 and integers greater than 2.
A semiconductor compound of a formula
- wherein R1 is selected from H, alkyl, fluorosubstituted alkyl, aryl and fluorosubstituted aryl moieties, said alkyl and fluorosubstituted alkyl moieties ranging from about C2 to about C10;
- each said x is an integer independently ranging from 0 to about 4;
- y and y′ is an integer independently selected from 1 and integers greater than 1;
- z is an integer selected from 0 and integers greater than 0;
- each said v is an integer independently selected from 1 and 2;
- and each said w is an integer independently selected from 0 and 1, wherein at least one of said x and z is 1, at least one of y and y′ is 1, and at least one of said v and said w is 1.
