New photoactive polymerizable monomers were synthesized in order to photomodulate the mechanical properties of photocurable materials. These monomers are end-capped by at least two polymerizable units (using irradiation wavelength λ1) connected by a spacer including at least one photocleavable unit (irradiation wavelength λ2≠ λ1) ie aryltriazene or 2-nitrobenzyl core. The photochemical behaviour of these systems was studied in solution ...
