Abstract:
1. A method of making semiconductor particles, the method comprising: a) providing a dendrimer comprising b) forming a crosslinked dendrimer by reacting the first crosslinkable groups and the second crosslinkable groups; c) cleaving by a chemical reaction both the first attachment group and the second attachment group; d) removing the core organic material or a derivative thereof from the crosslinked dendrimer to form a cored dendrimer having interior end groups; e) forming a coordinative bond or an ionic bond between a metal-containing precursor and the interior end groups within a central region of the cored dendrimer; and f) precipitating the metal-containing precursor to form a composite particle comprising a semiconductor particle within the central region of the cored dendrimer.
