Hello,
the following simple Org document
#+BEGIN_SRC org
,#+OPTIONS: LaTeX:dvipng ^:{}

This is small example $\exp^{\imath\phi}=\cos\phi+\imath\sin\phi$.
#+END_SRC

gives me wrong HTML export, see attached html file.

Emacs was started as
#+BEGIN_SRC sh
emacs -Q -l debug.el
#+END_SRC
where
#+BEGIN_SRC emacs-lisp
(setq load-path (cons "/usr/share/emacs/site-lisp/org" load-path))
(setq debug-on-error t)
(require 'org)
(require 'ox-html)
#+END_SRC

Does this mean that 'LaTeX:dvipng' is deprecated?

Org-mode version 8.0-pre (release_8.0-pre-270-g29a75d @/usr/share/emacs/site-lisp/org/)
