“…Lithographic methods can be applied to organic films when photosensitive groups are available. More recently, due to the possibility to use IR‐lasers in combination with IR absorbers for imaging, also thermal processes are used to create imagewise chemical changes in organic layers as we have shown for diazosulfonate polymer films 14. Since several years photo and thermolabile protecting groups for special functionalities, e.g., COOH or amino groups, are known and used mainly in peptide synthesis 15,16.…”

Photolabile terpolymers have been designed and used to prepare thin organic films covalently attached to glass and silicon substrates. For this, terpolymers containing photolabile protected amino functions introduced by N‐(N‐nitroveratryloxycarbonylaminopropyl)methacrylamide as well as (trimethoxysilyl)propylmethacrylate and MMA as comonomers have been synthesized via free radical polymerization. The nitro group containing protecting group leads to a retardation of the free radical polymerization. But complete removal of non‐reacted monomer from the reaction product without gelation of the anchoring groups was achieved. Thin films from these terpolymers were structured imagewise by UV laser light irradiation in order to create defined functional areas at the template surface ready for further modification and attachment of nanoobjects. The selective deprotection was verified by UV‐imaging and selective modification reaction using fluorescence labeling.Area selective UV imaging of a AMINE‐P7 film; presentation of the changes in optical density after UV laser irradiation.magnified imageArea selective UV imaging of a AMINE‐P7 film; presentation of the changes in optical density after UV laser irradiation.

“…However, given the results for diazosulfonate copolymers without any TMSPMA content prepared under similar conditions, [26,28] we expect M n 0 s of about 10 000 to 15 000 g Á mol À1 .…”

“…This is explainable by the loss of the hydrophilic diazosulfonate group in the decomposition process. In comparison to earlier studies on the wettability of spin-coated and irradiated diazosulfonate copolymers we have measured considerably higher contact angles, [28] even though the MMA content was similar. In these previous studies copolymers of MMA and methacrylamido-4-phenyldiazosulfonate (80:20) have been prepared also via spin-coating in about 50-nm thickness and from methanol solution.…”

“…[25][26][27] Thus, the patterning of 1-2-mm thick diazosulfonate copolymer films by UV light and IR laser irradiation was investigated. [28] These films were not covalently linked to the substrate. The metal ion exchange behavior of diazosulfonate polymers has been studied first using, e.g., Cr(III), Fe(II) and Pb(II) [29] and later Ag(I) ions.…”

An improved synthesis of photosensitive homopolymers containing aryltriazene chromophores covalently incorporated into the polymer backbone is reported. Such photopolymers proved to have promising properties for novel UV‐laser applications. A homologous series of new aryltriazene polymers with increasingly branched side chains (R = Me, Et, iPr, tBu) was synthesized and characterized. Homogeneous thin films with thicknesses from ≈15 to >150 nm were prepared by spin‐coating. Photodecomposition was studied in solution and on thin films. Polymers with increasingly branched and bulky substituents showed decreasing photodissociation rates. NMR studies suggested an enhanced hindrance of the N(2)–N(3) bond rotation in the aryltriazene moiety with increasing steric demand of the substituents.
