Pauloehrl, T., Welle, A., Oehlenschlaeger, K. K., & Barner-Kowollik, C. (2013) Spatially controlled surface immobilization of nucleophiles via trapping of photo-generated thioaldehydes. Chemical Science, 4(9).

A novel and very simple photochemical strategy that utilizes light as a facile means to provide spatio-temporal control for the direct covalent immobilization of nucleophiles is presented. The concept is based upon the efficient trapping of photogenerated thioaldehydes by amines, hydroxylamines, and thiols. Surface patterns of polymers and small molecules bearing pendant amine-, hydroxylamine- or thiol moieties were successfully generated and imaged in a time-of-flight secondary-ion mass spectrometry (ToF-SIMS) investigation. © 2013 The Royal Society of Chemistry.

19 citations in Scopus
Search Google Scholar™
21 citations in Web of Science®

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
