Developing novel emissive supramolecular assemblies with elegant architectures and tunable perfor-mance remains highly desirable yet ***,we report the design and synthesis of several 9.10-bis(diphenylmethylene)-9.10-dihydroanthracene-based metal organic assembles with aggregation-induced emission *** assemblies feature intriguing thermochromic and mechanochromic properties,ie.,distinguishable fuorescence responses in terms of emission wavelength and intensity un-der variable temperatures and ***,these assemblies can serve as excellent fluorescent sensors for the detection of polysaccharide *** to the differentiated charge type and den-sity,the assembles display distinct sensing mechanisms toward different polysaccharide *** study provides novel perspectives for the synthesis of buttrfly-like platinum(I)supramolecular coordi-nation complexes with multistimuli-responsiveness for polysaccharide *** will facllitate the development of stimuli-responsive materials.

The multiple sensing provides booming options to eliminate interference and ensure the accuracy of detection by mutually coupling and validating multiple data ***,we integrate the jigsaw-like multifunctional mini-pillar platform to perform multi-mode(electrochemical,fluorescence,surface-enhanced Raman scattering(SERS)and colorimetric)sensing in individual *** mini-pillar connector can parallelize together by specific concave-convex interface to form integrated jigsaw-like platform for multi-mode sensing,and each specific mini-pillar can be modified into the individual sensing unit to read the prescribed *** successfully implemented electrochemical,fluorescence,SERS and colorimetric detection by multiple signals coupling to reduce the false positive *** platform brings a promising clue of in-situ analysis and point-of-care testing for disease diagnosis and health monitoring.
