摘要：
Growing pores: Exposure of a bis-norbornene trithiocarbonate to long-wavelength UV light, or sunlight, in the presence of N-isopropylacrylamide (NiPAAm) led to well-defined norbornene-telechelic poly(NiPAAm) macromers. The macromers were end-linked with a tris-tetrazine via inverse-electron-demand Diels-Alder cycloaddition to generate polymer gels. Addition of new monomer, followed by exposure to sunlight, led to "photo-growth" of the network pores. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
