  the resulting MBBI⋅CB[8] complex binds to a series of aromatic second guests with Ka values ranging from 103 to 105 M−1. These complexation phenomena were supported by mass spectrometry, which confirmed complex formation, and a series of NMR studies that showed the expected upfield perturbation of aromatic peaks and of the MBBI methyl peaks. Surprisingly, the binding behavior of MBBI is strikingly similar

  描述了苯并双（咪唑鎓）盐（BBI）作为涉及大环主体葫芦[8]尿嘧啶（CB [8]）的超分子组装体的稳定和荧光组分的用途。CB [8]具有非同寻常的能力，能够紧密选择性地与水性介质中的两个客体结合，通常是作为第一客体的是甲基紫精（MV），然后是包含吲哚，萘或邻苯二酚的第二客体。基于相似的大小，形状和电荷，四甲基苯并双（咪唑鎓）（MBBI）被认为是MV的潜在替代品，它将增加来宾的葫芦库[8] uril。等温滴定热法（ITC）研究表明，MBBI以1：1的比例与CB [8]结合，平衡缔合常数（K a）值为5.7×10 5  M-1，并且所得的MBBI⋅CB[8]络合物以K a值为10 3到10 5  M -1的一系列芳族第二客体结合。这些络合现象得到了质谱的证实，质谱证实了络合物的形成，一系列的NMR研究表明，预期的芳香族峰和MBBI甲基峰的高场扰动。出乎意料的是，MBBI的结合行为与MV非常相似
• Postpolymerization Modification of Hydroxyl-Functionalized Polymers with Isocyanates

  The postpolymerization functionalization of hydroxyl-group terminated polymers (M-n in the range of 1000-6000 g mol(-1)) such as poly(ethylene glycol) (PEG), poly(N-isopropylacrylamide) (PNIPAM), poly(N,N-dimethylacrylamide) (PDMAM), and poly(tert-butyl acrylate) (PtBA) with a wide range of functional isocyanate derivatives such as azobenzene, and anthracene has been investigated. It was shown by H-1 and C-13 NMR, GPC, Fourier transform infrared spectroscopy (FTIR), and electrospray ionization mass spectrometry (ESI-MS) that a high degree of end-group conversion, typically >98%, with little or no formation of side products can be achieved at ambient temperature. PNIPAM, PDMAM, PtBA, and PHEAM polymers have been obtained by reversible addition-fragmentation chain transfer (RAFT) radical polymerization from a hydroxyl-group containing chain transfer agent (CTA). The formation of the carbamate has been shown to be compatible with the trithiocarbonate end-group of the RAFT polymers. Additionally, this approach allows for the direct functionalization of RAFT polymers without the need of additional steps such as deprotection or aminolysis of the CTA. This route was subsequently used for the preparation of a variety of side-chain functional polymers from poly(N-hydroxyethyl acrylamide) (PHEAM). Three different high yielding methods have been employed to prepare the isocyanates (R-NCO). Either amino or carboxylic acid precursors have been converted into the desired R NCO or hydroxyl group moieties have been reacted with an excess of 1,6-hexamethylene diisocyanate (HDI) to statistically form the monofunctional product.

  The present invention relates to the sector of self-diagnostic composite materials. In particular, the invention presents an agent, which can be cross-linked together with a curing agent in a matrix, e.g. an epoxy resin, and fibres, e.g., carbon fibre, in order to obtain a composite material containing a reporting probe capable of detecting stress, fatigue and microscopic cracks in the material with high spatial resolution and sensitivity.
