The present invention provides novel compositions suitable for use in an intermolecular photodeprotection reaction scheme. Such compositions include a chromophore compound and a second compound having a photocleavable group bonded to a protected functional group. Novel compounds which can used in intramolecular photodeprotection are also provided. These compounds have a chromophore moiety bonded to a photocleavable group, which itself is bonded to a protected group. The compounds and compositions disclosed herein can be used in two-photon and multi-photon excitation.

De telles compositions comportent un composé chromophore et un second composé possédant un groupe photoclivable lié à un groupe fonctionnel protégé. L'invention concerne également des composés novateurs pouvant être utilisés dans la photodéprotection intramoléculaire. Ces composés possèdent un groupement chromophore lié à un groupe photoclivable, qui est lui-même lié à un groupe protégé. Les composés et compositions de la présente invention peuvent être utilisés pour une excitation à deux photons et à multiples photons.

Photoremovable protectinggroups based on intramolecular electron transfer have been synthesized and studied. One molecule contains a N,N-dimethylaniline chromophore covalently linked to a phenacyl ester of acetic acid. UV photolysis of this molecule results in the release of acetic acid. Laserflashphotolysis experiments show that photolysis creates an intramolecular charge-transfer state that has a
