4-Nitrophenylaminoacetaldehyde acetal derivatives and polymeric materials prepared therefrom |
| abstract |
A compound of formulan n<IMAGE>n where R<1> to R<4> can represent C1-6 alkyl groups or a hydrogen atom, is disclosed. Also disclosed is a polymeric organic nonlinear optical material comprising a polymer such as acetalized polyvinyl alcohol having this 4- nitrophenylaminoacetaldehyde acetal as a side chain. The polymers are useful in the manufacture of optical devices such as waveguides. |
