Activated chemicals play a key role in the waterproof performance of cementitious capillary crystalline waterproofing materials (CCCW). We proposed sodium carbonate, sodium silicate, sodium aluminate, tetrasodium EDTA and glycine as activated chemicals of CCCW. The proportion of activated chemicals of CCCW was optimized by two key parameters evaluation of the second permeability ratio and pre-pressure self-healing rate for their self-healing ability of CCCW. Results show that sodium silicate has the most significant impact on the self-healing ability of CCCW. In the self-healing progress of CCCW, the consumption of Ca(OH)2 (CH) and the production of Calcium Silicate Hydrate (CSH) gel, calcium carbonate and ettringite were observed through XRD and SEM analysis. The white crystals with an average diameter of 0.2 mm are produced on both sides of cracks, and consequently the cracks were healed by the accumulation of crystals. The self-healing mechanism of CCCW was proposed based on the self-healing experimental results.

The luminescent liquid crystals (LLCs) are expected to solve the conflicts between the aggregation caused quenching and the requirement of aggregation or self-organization for LCs. Herein, we developed a new strategy of applying aggregation-induced emission (AIE) phenomenon to the molecular design of LCs towards LLCs. In this report, a calamitic liquid crystal based on tolane with AIE characteristics was successfully synthesized and the chemical structure was characterized by 1H, 13C NMR, and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) high-resolution mass spectra. The fluorescence behavior was studied by fluorescence spectroscopy and the liquid crystal phase behaviors were investigated by differential scanning calorimetry (DSC), polarized optical microscopy (POM). The crystal structure was obtained by X-ray diffraction crystallography with P1 space group. Results demonstrated that the sample was AIE active and the LC phases sequence during cooling was nematic, smectic C and smectic B phase.
