Abstract

Donor-π-donor, donor-acceptor-donor, and acceptor-donor-acceptor chromophores that hold great promise for 3D optical data storage and 3D microfabrication were tested. Results showed that in the case of donor-π-donor chromophores, the large absorption cross-sections arise from the symmetric re-distribution of charge from the donor-end groups to the conjugated bridge upon excitation. It was also shown that donor-π-donor chromophores exhibit increased sensitivity and recording speed over resins containing conventional photoinitiators.
