The present application discloses stilbene derivative compounds and phenylbenzofuran compositions, useful in the manufacture of dye-sensitized solar cells and other similar technology.

The present application discloses stilbene derivative compounds and phenyl-benzofuran compositions, useful in the manufacture of dye-sensitized solar cells and other similar technology.

The present disclosure is a stilbene-based compound or a salt thereof represented by a following formula (1), wherein a group X represents a nitro group or an amino group optionally having a substituent; a group Y represents an amide group optionally having a substituent or a naphthotriazole group optionally having a substituent; and p and q each independently represent an integer of 0 to 2. ##STR00001##

Voltage sensitive dyes comprising boron and related compositions and methods are provided. In some embodiments, a voltage sensitive dye comprises an electron acceptor comprising boron. The electron acceptor may be attached (e.g., covalently) to at least one electron donating group and at least one polar group. For instance, the electron acceptor may comprise optionally substituted boron dipyrromethene (e.g., optionally substituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene). The point of attachment and chemical nature of the electron donating group(s) and polar group(s) may be selected to impart beneficial properties to the voltage sensitive dye. For instance, the voltage sensitive dye may have an extended difference in the dipole moment between the ground and electronic states due at least in part to the position of the electron donating group(s). The voltage sensitive dyes, described herein, may have high specificity, high signal to noise ratio, fast responsivity, high voltage sensitivity, high photostability, and/or high brightness.

A fluorescent dye, as well as a preparation method and uses thereof, wherein the fluorescent dye is sensitive and specific to viscosity and has low background fluorescence; it can also be used as a fluorescent activated and lighted probe used for fluorescent labeling, quantification or monitoring of protein, enzymes or nucleic acid.

The present application relates processes that can be used to produce encapsulated benefit agents comprising a core and a shell that encapsulates said core, encapsulated benefit agents produced by such process and products comprising such encapsulated benefit agents as well as methods of making and using such products. Such process can be used to produce particles that offer the desired protection and release benefits when used in a varity of products.

The present application discloses stilbene derivative compounds and phenyl-benzofuran compositions, useful in the manufacture of dye-sensitized solar cells and other similar technology.

A dye composition dissolvable within a liquid crystal host device (including: polymer dispersed liquid crystal, polymer network liquid crystal, polymer stabilized liquid crystal, liquid crystal displays and similar devices), comprising eutectic mixtures of dichroic metallomesogen molecules. The aforesaid metallomesogen molecules comprise chromophore groups synthesized by physical and chemical mixing methods.

Novel fluorescent whitening agents, compositions or mixtures thereof with known fluorescent whitening agents, their preparation, and their use. The novel fluorescent whitening agents (FWAs) contain three structural subunits derived from 4,4-diamino-2,2-stilbenedisulfonic acid. The novel compounds and their mixtures with known FWAs show very good effectiveness as fluorescent whitening agents for cellulosic materials, in particular for paper.
