Novel 1,2-dioxetanes with improved chemiluminescent properties, such as signal intensity, S/N ratio, T½, etc. are provided by spiroadamantyl 1,2-dioxetanes, wherein the remaining carbon atom of the ring bears an alkoxy, aryloxy, or arylalkoxy substituent, and either a phenyl or naphthyl ring, this aromatic ring bearing, at the meta position on the phenyl group, or a nonconjugated position on the naphthyl ring,an OX moiety wherein X is an enzyme-cleavable group, which when removed from the dioxetane, leaves the oxyanion which decomposes with chemiluminescence, the aryl ring further bearing an electron-active substituent Z. The nature and placement of the Z substituent, at a position not adjacent the point of attachment to the dioxetane ring, strongly influences the properties of the dioxetane. Assays, as well as kits for the performance of those assays, include the dioxetane, an enzyme capable of cleaving the X group, and in certain cases, membranes and chemiluminescent enhancement agents.
