    摘要： A light-emitting composition comprising: a light-emitting group and a polymer comprising: a repeat unit of formula Ar1 wherein Ar1 is an arylene repeat unit which is unsubstituted or substituted with one or more substituents; and a repeat unit of formula (I): (I) wherein Ar2 and Ar3 each independently represent a C6-20 arylene group or a 5-20 membered heteroarylene group which is unsubstituted or substituted with one or more substituents and CB represents a conjugation-breaking group which does not provide a conjugation path between Ar2 and Ar3; wherein the polymer has a solubility in water or a C1-8 alcohol at 20° C. of at least 0.1 mg/ml. The composition may be a light-emitting polymer in which the polymer contains the light-emitting group. The light-emitting composition may be part of a particle containing the polymer and a matrix material, e.g. silica. The light-emitting composition may be used in an assay for detection of a target analyte.

    IPC分类号： G01N33/00

    摘要： A sensor system that removes responses from an interferent and/or corrects for baseline drift of a sensor to determine a presence, a concentration or a change in concentration of a target material in a gaseous environment. Fluid flowing into the system may be directed by a valve arrangement to either a first fluid flow path or a second fluid flow path. The target material may be absorbed by a filter material in the first fluid flow path. Fluid flowing along the second gas flow path passes directly to the sensor. Responses of the sensor to fluids from the first and second fluid flow paths may be used to determine a presence, concentration or change in concentration of the target material.

    摘要： An organic photodetector comprising an anode; a cathode; and a photosensitive organic layer between the anode and cathode, wherein the photosensitive organic layer comprises an electron donor material and an electron acceptor compound of formula (I): R11 and R12 may be, e.g. C1-20 alkyl and derivatives thereof or an aromatic or heteroaromatic group. R13-R16 may be, e.g. H, F, C1-20 alkyl and derivatives thereof. R20-R23 independently in each occurrence is selected from the group consisting of H, C1-20 alkyl and an electron-withdrawing group. Each X is independently O, S, Se or Te.
