Poly Vinyl Cinnamate Contrasts Leads Wavelengths - China

price: contact company for price

Poly(vinyl cinnamate) CAS: 9050-06-0 Under UV irradiation, poly(vinyl

cinnamate) (PVCi) films undergo cross-linking due to [2 + 2]

photocycloaddition between cinnamoyl groups. Consequently, electronic

configuration of lateral polymer groups changes and also leads to the

drop of the refractive index in the visible range. This mechanism is

studied with regards to the level of the electronic absorption of

cinnamate centered at 278 nm. It acts on refractive index by shifting

the absorption UV band. Most of the time, this influence vanishes in the

near infrared region (NIR). It is due to antagonist phenomena acting at

the expense of the index lowering. The causes analysis leads us to

optimize the irradiation spectrum, providing higher index contrasts

between irradiated and nonirradiated area. We show that strong index

changes can be achieved in PVCi film, up to 2.5 10-2 even in the NIR,

enabling us, for example, to perform optical photoprinting waveguides

for telecommunication wavelengths (1300-1550 nm).
